The Environmental Imperative Driving PFAS-Free Battery Innovation

The Hidden Environmental Cost of Modern Batteries

While lithium-ion batteries power our clean energy transition and digital revolution, few consumers realize these technological marvels contain per- and polyfluoroalkyl substances (PFAS)—persistent “forever chemicals” that pose significant environmental threats. As battery demand skyrockets with the electric vehicle revolution and renewable energy storage expansion, researchers and manufacturers are racing to develop alternatives that maintain performance while eliminating these problematic compounds., according to technology insights

Why PFAS Became Battery Industry Staples

Dr. Jacqueline Edge, an associate professor at the University of Birmingham, explains that battery interiors represent extreme environments. “Inside a battery can be a highly acidic, high temperature and high voltage environment,” she notes, requiring chemicals and materials that can withstand demanding conditions., according to according to reports

Fluorinated chemicals have proven ideal for these challenging applications due to their exceptional stability. Commercially produced batteries typically use polyvinylidene fluoride (PVDF), a PFAS compound, as an electrode binder, along with lithium hexafluorophosphate as an electrolyte salt. These materials provide the thermal and chemical stability necessary for reliable battery operation but come with significant environmental drawbacks., according to technology trends

The Recycling Challenge and Environmental Impact

The persistence of PFAS compounds creates substantial hurdles for battery recycling operations. “We are not really targeting recovery of the fluorinated content of batteries at the moment: we tend to focus on recycling the metals,” Dr. Edge explains. “These fluorinated chemicals make the recycling process very much harder, because you need to dissolve the fluorinated binder to be able to recover the cathode materials.”, as as previously reported, according to industry analysis

The environmental implications are concerning. PFAS compounds can persist in the environment for thousands of years, and current recycling infrastructure isn’t equipped to handle them effectively. “Because we’re not really geared up to recover the fluorinated compounds, they will basically just be released into the environment in various polluting forms,” warns Dr. Edge, highlighting the urgency of addressing this issue before scaling battery production further., according to recent research

Economic and Health Incentives for Change

The push for PFAS-free batteries extends beyond environmental concerns. Dr. Edge emphasizes the multiple benefits of finding alternatives: “From an economic point of view, from an occupational health point of view and from an environmental health point of view, it’s really worth trying to remove these chemicals.”, according to technology trends

With millions of electric vehicle batteries approaching end-of-life in the coming decade, developing safer recycling processes becomes increasingly critical. Removing PFAS would:

• Simplify recycling operations and reduce costs
• Improve workplace safety for battery manufacturing and recycling personnel
• Prevent long-term environmental contamination
• Create more sustainable battery lifecycles

Innovative Approaches to PFAS-Free Battery Manufacturing

Several companies are pioneering alternative manufacturing processes that eliminate PFAS while maintaining—or even enhancing—battery performance. Ateios Systems has developed a revolutionary approach that replaces traditional solvent-based methods with light-activated curing.

Rajan Kumar, CEO and founder of Ateios Systems, describes traditional battery manufacturing as “a slow, toxic and energy-intensive process, which has barely changed since the 1980s.” His company’s innovation uses electron curing to instantly harden battery materials without heat, toxic solvents, or lengthy drying steps. The process has been independently verified to contain no PFAS compounds.

The benefits extend beyond environmental considerations. “We have also seen enhanced battery performance, because this polymer has better quality adhesion,” Kumar reports. “And we have seen about 10% retention, which means another 40% usable capacity out of that battery.”

Closing the Loop: The Circular Battery Economy

Perhaps most significantly, PFAS-free batteries enable true circularity in energy storage. Kumar explains: “Our process also allows you to make the battery and when it’s done, it can come back to the factory, you break down the polymer and reuse the materials to make a new generation battery.”

This closed-loop system allows manufacturing and recycling to occur at the same facility, creating continuous supply chains that reduce waste and resource extraction. “Having that kind of circularity will be really essential for us as a human race to get to another level,” Kumar emphasizes.

Market Forces Accelerating Change

Recent regulatory and supply chain developments are adding urgency to the search for PFAS alternatives. China’s restrictions on key battery materials like graphite and lithium iron phosphate (LFP), combined with emerging PFAS regulations in multiple jurisdictions, are narrowing options for battery manufacturers.

Companies like Ateios are responding by developing fully domestic supply chains for PFAS-free battery components. Their American-sourced graphite and LFP electrodes can be manufactured at impressive speeds up to 80 meters per minute, demonstrating that environmental responsibility and manufacturing efficiency can coexist.

The Path Forward

The transition to PFAS-free batteries represents more than an environmental imperative—it’s becoming a business necessity. As regulations tighten and consumer awareness grows, manufacturers who pioneer safer alternatives will gain competitive advantage while contributing to a more sustainable energy future.

The search for PFAS-free battery solutions exemplifies how environmental challenges can drive innovation that benefits both planet and profit. With continued research and development, the next generation of energy storage technology may finally break free from its toxic legacy while delivering improved performance and recyclability.
